HTTP/2 Version Identification https://tools.ietf.org/html/draft-ietf-httpbis-http2-17#section-3.1 took a different approach to this issue. It defined the final string "h2"; said only implementations of the final, published RFC can use that; earlier implementations MUST NOT use that; they can use "h2-<draft-number>", eg "h2-17"; a note to the rfc-editor asked for this text to be remove in the final RFC. That avoids the risk of delays in the publication pipeline; but increases the risk that an implementation of an incompatible early draft ignores the text and uses the final id. It is probably a better compromise. -- James Manger -----Original Message----- From: Cfrg <cfrg-bounces@irtf.org> On Behalf Of Stephen Farrell Sent: Sunday, 16 August 2020 12:23 AM To: Christopher Wood <caw@heapingbits.net>; cfrg@irtf.org Subject: Re: [Cfrg] review of draft-irtf-cfrg-hpke-05 [External Email] This email was sent from outside the organisation – be cautious, particularly with links and attachments.

We probably should have done this from the start. Sure, I get the "why" and am fine with that. The only concern is that when the RG are finished and then hit "publication requested" it might take a while for the RFC number to be known (e.g. a few months). This draft, plus the esni and svcb drafts are likely to form a small cluster so that might well extend the delays some. If MLS were added to that cluster that might add more too. If OTOH, we ask the RFC editor to replace with a string we already know then I think that should reduce the need for breaking interop after the cluster-induced delay. (It's true that for this to be useful, the same trick might need to be more widely adopted, but starting with hpke seems fine as others in the putative cluster would depend on this and not the other way about.) Cheers, S.
